Specific embodiment
The present invention is described in detail With reference to embodiment.
Present system is as depicted in figs. 1 and 2, including watertight compartment 1, the first hydrophone 2, the second hydrophone 3, third water
Listen device 4, the 4th hydrophone 5 and bracket 6；Bracket 6 connects watertight compartment 1, and bracket 6 is set there are four top, the first hydrophone 2, second
Hydrophone 3, third hydrophone 4, the 4th hydrophone 5 are respectively placed in four tops of bracket 6, and bracket 6 can form positive 4 face in space
The side length of body, positive 4 face body can be according to the object variation of research.Watertight compartment 1 include capture card 7, storage card 8 and battery 9, first
Hydrophone 2, the second hydrophone 3, third hydrophone 4, the 4th hydrophone 5 connect capture card 7, capture card 7 by signal wire respectively
External host computer, storage card 8 are connected by signal wire, battery 9 connects capture card 7 as the power supply of capture card 7.First hydrophone 2,
Two hydrophones 3, third hydrophone 4, the 4th hydrophone 5, bracket 6 and watertight compartment 1 itself and its between use watertight technology system
Make, to meet pressure-resistant demand.Watertight compartment 1 needs that plastics, stainless steel or titanium alloy is selected to make according to pressure resistance.Hydrophone signals
It is accessed by underwater electrical connector.PC control signal is accessed before system starts, is no longer accessed after system starts,
Array from capacitance type to work.Using the running parameter of host computer computer setting hydrophone array, including starts acquisition time, adopts
Sample frequency, acquisition mode etc..Wherein acquisition mode has continuous acquisition, interval acquisition and 3 kinds of modes of triggering collection.When system works
In the mode of triggering, only one hydrophone is worked using low-power consumption mode, and when detecting has signal in environment, 4 water are listened
Device all starts synchronous acquisition.
Before system starts, the running parameter of system is set by host computer computer, including starts acquisition time, sampling
Frequency, acquisition mode etc..Wherein acquisition mode has continuous acquisition, interval acquisition and 3 kinds of modes of triggering collection.System starts
Afterwards, storage card is recorded in collected signal.System exhausts 2. memory card capacities and exhausts to reach with 3. in 1. electricity of satisfaction
System setting time, this 3 conditions for the moment, stop working.
